NSC622608 with VISTA using STDNMR and molecular modeling enabled the identification of a potential binding site in VISTA for NSC622608. Screening NSC622608 against a library of single-point VISTA mutants revealed the key residues in VISTA interacting with NSC622608. Further structural optimization resulted in a lead with submicromolar VISTA bindingaffinity. The lead compound blocked VISTA signaling
V 域 Ig T 细胞激活抑制因子 (VISTA) 是一种免疫检查点,可影响 T 细胞攻击肿瘤的能力。基于 FRET 的高通量筛选将 NSC622608 鉴定为 VISTA 的第一个小分子配体。使用 STD NMR 和分子建模研究 NSC622608 与 VISTA 的相互作用,能够在 VISTA 中鉴定 NSC622608 的潜在结合位点。针对单点 VISTA 突变体库筛选 NSC622608 揭示了 VISTA 中与 NSC622608 相互作用的关键残基。进一步的结构优化导致具有亚微摩尔 VISTA 结合亲和力的先导物。先导化合物在体外阻断 VISTA 信号传导,增强 T 细胞增殖,并在表达 VISTA 的癌细胞系存在的情况下恢复 T 细胞活化。
